Application filed June 19, 1925. Serial 38,279.

The invention relates generally to convcyers and particularly to a conveyer adapted to remove viscous material such as glue, putty or the like from a container. s

An object of the invention is to provide a device thatv can be inserted in a container such a barrel or the like and be held securely rein and adapted to remove heavy material from the container.

Another object of the invention is to pro'- vide anejecting conveyer having an augerbit formed on its end, arranged to be used to cut a hole of the proper size in the container hold the casing and to cut into the contentsl of said container to force it out.

Another object of theinvention is to provide a conveyer with means for forcing material from a container intothe conveyor cas-k ing from theend, and valso having an opening on top to permit any material that will, to fall into the conveyor casing by gravity.

Another object of the invention is to provide the portion ofthe conveyor casing eX- tending beyond the container with an outlet opening and means for closingand sealing it substantially hermetically. i 1 Another object of the invention is to provide a relatively simple method of mounting the device in the barrel after the auger-bit has out ther hole'therein.

Another object of the invention is to provide means for preventingaxial displacement of the rotatable conveyer in either direction and to provide means for operating said conveyer.v l

The foregoing andsuch objects and advantages as may be pointed out or appear as this description proceeds are. attained in the preferred structural embodiment illustrated in the accompanying drawings wherein:

Fior. 1 is a side elevational view showin@i al b b barrel with the device of the present invention shown in operative position.

Fig. 2 is a longitudinal sectional view through the conveyor and a vertical section through a fragment of the container.

Fig. 3 is a cross sectional View taken on line 3-3 of Fig. 2. l

Fig. 4 is a fragmental perspective view showing the auxiliary inlet opening and the auger-bit- Fig. 5 is an elevational view showing the auger-bitcasing and a portion of the screw conveyer.

In 1 of the drawings 5 indicates a stand upon whichthe container or barrel 6 is supported, and Z represents the conveyer. as a whole mounted in operative position.

e conveyer casing is made in two sections @and 9. The section 8, asillustrated, 4is of tubular formation and is provid-ed with an opening 11 in its upper surface, to permit materialfroin theV container to drop therethrough by gravity, into the path of the screw convey-er. One end of the casing 8 isvprovided with internal threads 19, adapted to engage the companion yexternal threads pro` vided on oneend of the other section .9 of the casing. f f

The casing section 9 has a relatively large bore extending for a portionof its length, and

a concentric bore of reduced diameter extend@ ina' from the first named bore through the remaining part of the casing section 9,7which latter bore functions as a bearing for the yshaft of thegconveyer.

A screw conveyor 13y of the conventional.`v` type is rotatably mounted within the casing v8 and has an Vauger-bit 19 formed integral therewith on the end. This auger-bit serves to bore the hole in the side of the ,barrel 1n which the device is mounted, and thereafter assists in discharging the contents of the barrel. It will be noted that this auger-bit is of a diameter substantially equal to the outer diameter of the tubular casing section 18. A central shaft 14 extends from the con,-`

veyer outwardly through the ,bore of reduced diameter, formed in the section 9 of the casing, and has operating means, such as a crank 15 secured thereto.V j y A collar 16 is secured to the shaft 14 by means of a counter sunk set screw or the like,

kto prevent axial displacement ofthe shaft.`

the end of the casing sectionB, or between the collar 16 and the. end bearing portion of the 1 casing section 9.

An internally threaded bore 21 is provided in the end of the casing section 9, to permit of packing 29 being placed therein. A gland 23 is slidably -fit-ted over the shaft 14,to be adjusted to position by the gland nut 24.

An out-let opening 25 is provided in the cas ing section 9, having a rotatable closing member 26 snugly fitted thereover. A companion opening 27 provided in the closing nieinber of substantially the saine size as the open- 25 is arranged to register with it in one position, and to close it in another position. A slot 28 is provided in said closing ineniber to engage a screu7 29, providing a stop, to liinit its angle of rotation.

rl'he auger-bit is usually placed to engage the container at approximately the location of the bung hole; it then drills out the bung hole or a part of it, and forces itseliI inwardly; whereupon the threaded portion 3l of the casing section 9 is screwed into the hole cut in the barrel Wall by the auger-bit, -which securely holds the device in the barrel. The closing iiieiiiber 26 is next revolved until its opening registers with the opening in the casing. t will be obvious that as the crank is turned the conveyor will torce the nia-terial in the barrel outwardly 4through the casing and discharge it'tlirougli the outlet opening. Y

I do not intend to be limited to the particular details herein shown and described, as it Will be obvious that the foregoing is merely an exemplary embodiment of the invention.

lfclaiin: i

l. In a conveyer discharging device for insertion in barrels and like containers, a bit for boring through the Wall of the barrel, a screw conveyer in continuation oit saidbit, and ineens for supporting said screw eon- Y veyer in said barrel.
